How To: Send an Arc/INFO GRID or coverage through email or FTP


Often it may be necessary to send an ESRI GRID format file over the Internet. This can be problematic due to the file structure of GRID's. The instructions provided below explain how to package a GRID file so that it can easily be sent by way of email, FTP, or other means of electronic transmission.


  • If ArcInfo Workstation is installed, the GRID file can be converted to an interchange file (e00) in ArcGIS Desktop
    This is done though ArcToolbox using the following geoprocessing tool: Coverage Tools > Conversion > From Coverage > Export to Interchange File.
    1. From the Export to Interchange File tool, select GRID as the feature type.
    2. Specify your GRID as the Input Dataset. Specify a name for the output file.
    3. Click OK to export the GRID to an interchange file. This file can be sent easily as an attachment to an email or by way of FTP.
  • If using an ArcView, ArcEditor, or ArcInfo license (without workstation installed), the procedure involves creating an archive of both the info and grid directories for the GRID being transmitted.

Follow the steps below to create an archive file containing the proper directory structure:

  1. In ArcCatalog create a new folder.
  2. In ArcCatalog copy your GRID to the new folder.
  3. In Windows Explorer use compression/archiving software to create a new archive file, such as .zip, .rar, .gz. When creating this file, make sure that it is being created for the newly created folder rather than the files within it. Most compression/archiving software allow for the compression of entire folders including the files contained within.
  4. Once the files have been archived/compressed, they are ready to be sent as attachments.
